Senior Software Engineer - Autonomous Accounting

At Synthetic we are synthetically recreating the professional service of bookkeeping using AI. Our product processes financial data, manages bookkeeping workflows, and communicates with customers autonomously. Read more about us in Betakit and Axios.

We are the founding team that previously built Bench Accounting from an idea to a successful business with >$100M raised and >600 employees, and Teal (acquired by Mercury). We're back in the SMB accounting space, this time working on a bigger idea with even greater potential.

Synthetic was founded in November 2025. We're a five person team so far. We have early test customers and a working prototype of our product that's advancing daily. We're seeking someone smart and hungry to join up and help build the next iterations of the product. We are building in San Francisco. We work 6 days a week in person to make our product a reality.

We're looking for people of exceptional competence to join our team. If this is you, and you want to work on the future of autonomous professional services, apply.
